New features
------------

* Speed-up ECC performance. ECDSA is 33 times faster on the NIST P-256 curve.
* Added support for NIST P-384 and P-521 curves.
* ``EccKey`` has new methods ``size_in_bits()`` and ``size_in_bytes()``.
* Support HMAC-SHA224, HMAC-SHA256, HMAC-SHA384, and HMAC-SHA512 in PBE2/PBKDF2.

Resolved issues
---------------

* DER objects were not rejected if their length field had a leading zero.
* Allow legacy RC2 ciphers to have 40-bit keys.
* ASN.1 Object IDs did not allow the value 0 in the path.

Breaks in compatibility
-----------------------

* ``point_at_infinity()`` becomes an instance method for ``Crypto.PublicKey.ECC.EccKey``, from a static one.

------

* Fix bug at the end of the test session when a call to ``patch.stopall`` is done explicitly by
user code. Thanks `craiga`_ for the report (`137`_).
